  • Anyone who really listens here MUST understand the reality of evolution. It's a logical inevitability.

  • @taicleis This need to be taught much better in school. Also, Carl Sagan is a god. :)

  • This is wonderful stuff - thanks for posting it to YouTube! One minor comment: Carl misspoke when discussing the crinoids. These amazing organisms are indeed still around today.
